I've made Ubuntu 14.04 dual boot with Windows 8.1., but after installing Ubuntu everything is working well, but after 1-2 day(s), I don't see my boot option menu after powering on my system; it directly boots into Windows 8.1.
To fix it I ran the following commands in the Ubuntu terminal:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo sh -c "sed -i 's/trusty/saucy/g' /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
Then everything ran well but after some time I don't see boot option menu after powering on the device.
Is there any permanent solution for this issue?
/etc/default/grub
, is there a non-zeroGRUB_TIMEOUT
?sudo update-grub
?
